Energy Manager Design for Microgrids. On-site energy production, known as distributed energy resources (DER), offers consumers many benefits, such as bill savings and predictability, improved system efficiency, improved reliability, control over power quality, and in many cases, greener electricity.

Additionally, DER systems can benefit electric utilities by reducing congestion on the grid, reducing the need for new generation and transmission capacity, and offering ancillary services such as voltage support and emergency demand response. Work within the CERTS DER team at the Ernest Orlando Lawrence Berkeley National Laboratory has led to development of software tools for microgrid design and operation. The DER Customer Adoption Model (DER-CAM) chooses economically optimal sets of DER devices to install for a given site. Additionally, the Site Energy Supply and Use Model (SESU) simulates operation of an installed microgrid and can be used as a testing ground for proposed EM strategies.

Author(s):Cheah Peng Huat - 南洋工科大学 Siow Lip Kian - 南洋工科大学 Liang Hong Zhu - 南洋工科大学 Vo Quoc Nguyen - 南洋工科大学 Nguyen Dinh Duc - 南洋工科大学 Gooi Hoay Beng - 南洋工科大学 Students at the Laboratory for Clean Energy Research (LaCER) in the School of Electrical and Electronic Engineering (EEE) at Nanyang Technical University (NTU) created a microgrid prototype.

It consists of energy resources such as solar photovoltaics (PVs), wind turbines, fuel cells, and battery banks. The entire microgrid is controlled by the Web-based MEMS server, which controls and monitors different aspects of power management. We developed software programs to manage information collected from the sensors and perform load control and generation dispatch. Figure 1 shows the interface diagram between the database and different software modules. Advanced Sensing and Communication System The microgrid testbed uses a programmable AC source to test the stand-alone microgrid.

These systems are made possible by two-way communication technology and computer processing that has been used for decades in other industries. They are beginning to be used on electricity networks, from the power plants and wind farms all the way to the consumers of electricity in homes and businesses. They offer many benefits to utilities and consumers -- mostly seen in big improvements in energy efficiency on the electricity grid and in the energy users’ homes and offices. For a century, utility companies have had to send workers out to gather much of the data needed to provide electricity. The workers read meters, look for broken equipment and measure voltage, for example. The “grid” amounts to the networks that carry electricity from the plants where it is generated to consumers.

Grid or Off-Grid?
Bob Bruninga, WB4APR If you have no access to the GRID, you have no choice, you have to go ... off-grid!

But if you have the grid and are considering going off-grid or using batteries for any reason, please review this page and also join our discussion group.

Staying on-grid can give you nearly triple the power for about the same cost and avoid battery maintenance for the rest of your life. Costs are so low you can now buy a DIY 3.7 kW system from COSTCO for $13,500. Here are some other web pages related to my experiences with home solar power:
What Is A Smart Solar Inverter?
Smart microinverters can help meet advanced grid functionality and operations & maintenance requirements.

By: Raghu Belur, SPW Contributor The growth of the U.S. solar market over the past five years has been remarkable, with the total number of photovoltaic installations climbing into the hundreds of thousands. This is impressive, but it’s still just a drop in the bucket compared to the tens of millions of rooftop and ground-mount PV systems that will be deployed during the next few decades.
